Abstract

The invention relates to a joint prosthesis (11) with the head cap (29) connected to a shaft piece (13) which may be anchored in the bone, by means of a collar piece (21). Said collar piece (21) is coupled to the shaft piece (13) by a joint head (25) in a ball-jointed manner. The articulation surfaces between the joint cavity (19) in the shaft piece (13) and the articulation head (25) on the collar piece are embodied such that on pressing the articulation head (25) to the base of the joint cavity (19), edges or projections on the one articulation surface engage with the other articulation surface lying on a virtually spherical surface. It is thus possible to achieve a ball-joint like articulation, whereby the spherical surfaces may have a relatively large production tolerance without the above affecting the clamping connection between the articulation surfaces.

Dadurch wird ein Presssitz zwischen den Endoprothesenteilen erreicht This is a press fit between the Endoprothesenteilen is achieved
  • Aus der EP-A- 0 712 617 ist eine Humeruskopfprothese bekannt, bei der eine über einen Stiel mit einer Kopfkalotte verbundene Anlenkkugel in einer Grube mit hohlkugeligem Grund an einem Schaftteil angelenkt ist. From EP-A-0712617 a humeral head prosthesis is known in which a connected via a shaft with a head cap articulation ball is articulated in a pit with hohlkugeligem base to a stem portion. Zur Fixierung der Anlenkkugel in der Grube sind eine oder mehrere Madenschrauben vorgesehen, die durch das Schaftteil hindurch gegen die Anlenkkugel geschraubt werden können. For fixing the articulation ball in the hole one or more set screws are provided which can be screwed through the shaft member passes against the articulation ball. In einem Ausführungsbeispiel wird mit der Madenschraube die c-förmig aufgeschnittene Anlenkkugel zusammengepresst, um den in einer zentralen Bohrung in der Anlenkkugel steckenden Stiel darin festzuklemmen. In one embodiment, the c-shaped cut articulation ball is pressed together to clamp the end plugs in a central bore in the articulation ball stem therein with the set screw. Es ist in einem anderen Ausführungsbeispiel eine Madenschraube vorgesehen, welche entlang der Stielachse durch die Anlenkkugel und gegen den Grubengrund geschraubt werden kann. There is provided in another embodiment of a grub screw which can be screwed along the shaft axis through the articulation ball and against the pit bottom. Mit dieser Schraube wird die Anlenkkugel gegen die Öffnung der Grube gepresst, durch die der Stiel aus der Grube vorsteht In einem weiteren Beispiel sind zur Indexierung der Stellung der Anlenkkugel in der Grube mit Vertiefungen in der Kugeloberfläche zusammenwirkende Noppen am Grubengrund vorgesehen. With this screw, the articulation ball is pressed against the opening of the pit, by projecting the stem out of the pit In another example, the articulation ball in the pit with recesses in the spherical surface cooperating knobs are provided on the pit base for indexing the position.
  • Aus der WO 99/34756, die der FR-A-2 773 469 entspricht, ist eine Gelenkprothese gemäß dem Oberbegriff von Anspruch 1 bekannt, bei welcher in einer halbkugeligen Vertiefung im Schaftteil ein darin kugelgelenkartig verschwenkbares Halsteil angelenkt ist Das Halsteil besitzt eine halbkugelige Anlenkfläche und eine gegenüber einer Achse durch derer Kugelmittelpunkt exzentrische Konusfläche zum Aufstecken einer Gelenkkalotte. From WO 99/34756 which corresponds to FR-A-2773469, a joint prosthesis according to the preamble of claim 1 is known in which in a hemispherical recess in the shaft part, a therein a ball joint pivotable neck portion hinged The neck portion has a semi-spherical articulation surface and a relative to an axis eccentric by which ball center conical face for plugging in a Gelenkkalotte. Das Halsteil weist eine von der Kalottenseite her offene Ausbohrung mit einem halbkugeligen Grund. The neck portion has an open bore of the Kalottenseite ago with a hemispherical surface. Mit dem Grund wirkt eine in die Ausbohrung eingeführte, durch eine Öffnung im Grund der Ausbohrung hindurch in das Schaftteil einschraubbare Schraube mit Kugelkopf. With the base acts an inserted into the bore, can be screwed through an opening in the base of the bore and into the screw shaft part with ball head. Die Kugeloberflächen der halbkugeligen Vertiefung im Schaftteil, der Anlenkfläche am Schaftteil, des Grundes der Ausbohrung und des Schraubenkopfes müssen den gleichen Mittelpunkt aufweisen. The spherical surfaces of the semi-spherical recess in the shaft part, the articulation on the shaft part, the bottom of the bore and the screw head must have the same center. Die jeweils zwei zusammenwirkenden Hohl- und Vollkugeloberflächen müssen zudem sehr exakt hergestellt und den gleichen Radius aufweisen. The two co-operating hollow and solid spherical surfaces must also very precisely manufactured and have the same radius. Kleinste Abweichungen von den Idealabmessungen führen dazu, dass das Halsteil mit dem Schaftteil nicht genügend fest verbunden werden kann, um eine unbeabsichtigte Verschwenkung des Halsteils gegenüber dem Schaftteil während des Gebrauchs des Gelenks sicher zu verhindern. The smallest deviations from the ideal dimensions cause the neck portion to the shaft portion may not be sufficiently firmly attached to prevent inadvertent pivoting of the neck portion towards the shank portion during use of the joint safely. Die dazu erforderliche Präzision der Kugeloberflächen erweist sich jedoch als sehr schwierig zu erreichen. However, The required precision of the spherical surfaces turns out to achieve very difficult.
  • Die DE-U-299 18 589 stellt sich zur Aufgabe, genau diesen Nachteil von zusammenwirkenden Kugeloberflächen zu vermeiden. DE-U-299 18 589 has as its object, just to avoid this disadvantage of cooperating spherical surfaces. Sie schlägt dazu eine Endoprothese für eine Schulter vor, bei der in einem Schaftteil ein Drehstück angeordnet ist, das lediglich um eine erste Achse drehbar ist An diesem Drehstück ist ein Richtstück um lediglich eine zweite Achse verschwenkbar angelenkt Auf dem Richtstück kann eine Kopfkalotte angeordnet werden. It proposes to before an endoprosthesis for a shoulder, in which a rotating piece is disposed in a shaft part which is only rotatable about a first axis on this rotating piece of a directional piece is by only a second axis coupled pivotably on the directional piece can be a spherical cap are arranged. Das Richtstück erstreckt sich entlang einer Halsachse, die - dank dem sich die erste und die zweite Achse queren - ähnlich wie bei einem Kugelgelenk in jede gewünschte Lage gebracht und darin festgestellt werden kann. The directional piece extends along an axis of the neck, which - thanks to which the first and the second axis cross - similar to a ball joint in any desired position and can be brought found therein.
  • Die DE-U-29918 589 lehrt damit, ein Kugelgelenk zu meiden und die Kugelgelenkbewegung dadurch nachzubilden, dass sie in zwei unabhängige Bewegungen um zwei diskrete Achsen aufgeteilt wird. The DE-U-29918 589 teaches order to avoid a ball joint, and track the ball joint movement in that it is divided into two independent movements about two discrete axes. Die Anlenk- und Reibungsflächen zwischen Schaftteil, Drehstück und Richtstück sind dank der Vermeidung von Kugelflächen Oberflächen von Rotationskörpern wie Zylinder, Torus und Konus. The articulation and friction between stem portion, rotating piece and directional piece are due to the replacement of spherical surfaces surfaces of solids of revolution such as cylinder, torus, and cone. Diese Oberflächen sind einfacher genügend präzise herstellbar. These surfaces are simple enough precision to produce.
  • Zum Feststellen der Schwenkbewegung des Richtstückes gegenüber dem Drehstück wird vorgeschlagen, dass sich die zusammenwirkenden Anlenkflächen vorteilhaft lediglich derart entsprechen, dass eine Linienberührung zwischen ihnen stattfindet. For detecting the pivotal movement of the directional piece relative to the rotary piece is proposed that the cooperating articulation surfaces advantageously correspond only to such that a linear contact between them occurs. Dazu kann die Anlenkfläche am Drehstück als Rinne mit zwei in einem Winkel zueinander stehenden ebenen Flächen ausgebildet sein. For this, the articulation surface may be formed on the rotating piece as a groove with two mutually in an angle with flat surfaces. Es kann auch eine Bohrung im Richtstück, an der der Kugelkopf einer Schraube anpresst, konisch ausgeführt sein. It may also be a bore in the directional piece, on which the ball head of a screw presses, be conical. Es wird weiter angeregt, dass die Anlenkflächen auch Kanten und Dome aufweisen können, die beim Festziehen der Schraube in die Gegenfläche einpressbar sind. It is further suggested that the articulation surfaces may also have edges and Dome, which can be pressed when tightening the screw into the mating surface. Ein Beispiel dazu ist nicht wiedergegeben. An example is not played.
  • Aufgabe der Erfindung OBJECT OF THE INVENTION
  • Es ist Aufgabe der vorliegenden Erfindung, bei einer Gelenkprothese mit einem im Knochen verankerbaren Schaftteil und einem kugelgelenkig daran angelenkten Halsteil und einer auf dem Halsteil angeordneten Kopfkalotte, sowohl die Fertigungstoleranzen für die am Kugelgelenk beteiligten Anlenkflächen als auch die Zuverlässigkeit der Immobilisierung des Kugelgelenks gegenüber dem Stand der Technik zu erhöhen. It is an object of the present invention, in a joint prosthesis with an anchoring in the bone shaft portion and a ball joint articulated thereto neck portion and, arranged on the neck part of the ball head, both the manufacturing tolerances for the involved in the ball joint articulation surfaces as well as the reliability of the immobilization of the ball joint over the prior to increase the art.
  • Beschreibung der Erfindung Description of the Invention
  • Erfindungsgemäss weist bei einer Gelenkprothese gemäss dem Oberbegriff des Patentanspruchs 1 eine erste der beiden zusammenwirkenden Anlenkflächen wenigstens eine Kante und/ oder Spitze auf. According to the invention in a joint prosthesis according to the preamble of claim 1 is a first of the two co-operating articulation surfaces at least one edge and / or tip. Zudem sind die Anlenkflächen bezüglich Form derart ausgebildet, dass sich lediglich ein oder mehrere Berührungsbereiche zwischen der Kante und/oder Spitze der ersten Anlenkfläche und der auf einer virtuellen Kugeloberfläche liegenden zweiten Anlenkfläche ergeben. In addition, the articulation surfaces are formed in such a shape with respect to that arising only one or more areas of contact between the edge and / or top of the first articulation surface and lying on a virtual spherical surface of the second articulation. Ferner sind die Anlenkflächen bezüglich Material derart ausgebildet, dass unter Einwirkung der beim Anpressen auftretenden Druckkräfte wenigstens die zweite Anlenkfläche im Berührungsbereich durch die Kante und/oder Spitze der ersten Anlenkfläche plastisch verformbar ist. In addition, the articulation surfaces in material are designed such that under the action of the pressure forces occurring during pressing of the second articulation surface in the contact region by the edge and / or top of the first articulation is at least plastically deformable.
  • Dadurch wird beim Anpressen des Pressteils wenigstens eine Kante oder Spitze der einen Anlenkfläche in die zweite Anlenkfläche eingegraben und so eine Verzahnung oder Verkrallung der beiden Anlenkflächen erreicht Die Verzahnung erlaubt die Toleranzen bei der Fertigung zu erhöhen. This buried during pressing of the pressing member at least one edge or tip of the articulation in a second articulation and so a tooth or claw of the two articulation reaches the teeth allows the tolerances in the manufacture to increase. Es wird daher trotz nicht übereinstimmender Flächenform und trotz relativ grosser Massungenauigkeiten ein Kugelgelenk geschaffen, das zuverlässig immobilisiert werden kann. It is therefore, despite not matching surface shape and despite relatively large dimensional inaccuracies created a ball joint which can be reliably immobilized. Für eine Verschwenkung oder Verdrehung des einmal befestigten Anlenkkopfes gegenüber der Anlenkmulde ist eine Verformung des Materials und sind daher sehr hohe Kräfte erforderlich. For a pivoting or twisting of the once attached articulation head in relation to the articulation chamber is a deformation of the material and very high forces are therefore necessary. Dennoch ist der Anlenkkopf in der Anlenkmulde geführt und kugelgelenkig verschwenkbar, solange das Pressteil nicht fest angepresst ist, sondern lediglich anliegt. Nevertheless, the articulation is guided in the joint cavity and pivotable ball joint, as long as the pressing member is not pressed firmly, but merely rests.
  • Die Gelenkprothese weist ein im Knochen verankerbares Schaftteil auf. The joint prosthesis includes a stem portion anchored in the bone. Dieses ist in bekannter Art auf den Knochen abgestimmt und wird dazu allenfalls aus einem Set von Schaftteilen ausgewählt. This is matched in a known way to the bone and to select most of a set of shaft parts. Am Schaftteil ist ein Halsteil angelenkt, welches eine Halsachse definiert. On the shaft part, a neck part is hinged, which defines a collar axis. Das Halsteil ist zur Aufnahme einer Kopfkalotte ausgerüstet oder Teil der Kopfkalotte. The neck part is equipped for receiving a ball head, or part of the ball head. Weiter ist die Gelenkprothese auch mit einer Kopfkalotte bestückt, welche auf die mit der Kopfkalotte zusammenwirkenden Gelenkpfanne ausgelegt ist. Furthermore, the joint prosthesis is fitted with a head cap, which is designed to cooperate with the ball head joint socket. Die Kopfkalotte ist möglichst an die entfernte natürliche Kalotte angenähert geformt und wird deshalb allenfalls auch aus einem Set von Kalotten ausgewählt. The ball head is shaped as possible closer to the remote natural dome and is therefore possibly also selected from a set of caps. Die Gelenkprothese weist ferner wenigstens ein Pressteil zum Anpressen des Halsteils an das Schaftteil und Mitteln zum Verbinden von Pressteil und Schaftteil auf. The joint prosthesis further includes at least a pressing member for pressing the neck portion to the shaft portion and means for connecting the pressure piece and the shaft part. Für die Anlenkung des Halsteils am Schaftteil ist entweder am Halsteils oder am Schaftteil eine Anlenkmulde und am andern Teil ein in der Anlenkmulde anzuordnender Anlenkkopf ausgebildet der Anlenkkopf ist in der Anlenkmulde wenigstens um zwei senkrecht zueinander stehende Achsen verschwenkbar bzw. verdrehbar. For the articulation of the neck portion on the shank part is either the neck portion or the shaft portion of a joint cavity and at the other part is formed a to be arranged in the articulation joint head of the joint head can be pivoted or rotated in the articulation at least two mutually perpendicular axes. Je nachdem, ob die Gelenkpfanne auch ersetzt wird oder nicht, weist die Gelenkprothese auch eine künstliche im Knochen verankerbare Gelenkpfanne auf. Depending on whether the socket is also replaced or not, the joint prosthesis also includes an artificial anchored in the bone joint socket. Bleibt die natürliche Gelenkpfanne erhalten, wirkt die Kopfkalotte mit dieser zusammen. Preserving the natural joint socket, the ball head cooperates with this.
  • Die plastische Verformung eines Berührungsbereichs in der Anlenkmulde oder eines Berührungsbereichs an der Anlenkfläche des Anlenkkopfes führt nicht nur dazu, dass die notwendige Präzision der Teile innerhalb herkömmlicher Herstellungstoleranzen liegen kann und keine erhöhten Anforderungen an die Herstellung und die Überprüfung der Masslialtigkeit der Teile stellt. The plastic deformation of a contact area in the joint cavity or a touch area at the articulation surface of the articulation head not only leads to the fact that the necessary precision of the parts may be within the conventional manufacturing tolerances and provides no increased requirements on the manufacture and inspection of the Masslialtigkeit of the parts. Die Verformung der Anlenkfläche führt auch zu einer unverschwenkbaren Verbindung zwischen Schaftteil und Halsteil. The deformation of the articulation surface also results in a unverschwenkbaren connection between the shaft portion and neck portion. Im verformten Bereich können bei einer Verpressung der Anlenkflächen beide oder auch nur eine beteiligte Fläche verformt werden. In the deformed region may both or only one surface involved are deformed at a compression of the articulation surfaces. Ist es vorwiegend das Halsteil, welches die Verformung erfährt, kann dieses, zB bei einer Revision der Gelenkprothese, erneuert werden, ohne dass das Schaftteil ausgewechselt werden muss. Is it mainly the neck part, which undergoes deformation, this can, for example, be in a revision of the joint prosthesis, renewed without the shaft part must be replaced.
  • Weisen die Berührungsbereiche zwischen dem Grund der Anlenkmulde und dem Anlenkkopf eine oder mehrere punktuelle Berührungen auf, oder auch eine oder mehrere durchgehende oder unterbrochene Linienberührungen, so ist in diesen Bereichen die Höhe des ausgeübten Drucks umgekehrtproportional zur Grösse der Berührungsbereiche. Have the contact areas between the base of the articulation and the articulation, one or more selective touches on, or one or more continuous or discontinuous line contacts, it is in these areas, the amount of pressure applied is inversely proportional to the size of the contact areas. Dadurch können stärkere Verformungen erreicht werden. This greater deformations can be achieved.
  • Ist eine der Anlenkflächen durch eine oder mehrere Körperkanten oder eine oder mehrere Körperspitzen, und die andere Anlenkfläche durch einen Flächenbereich gebildet, so werden die Körperspitzen und Körperkanten in die andere Anlenkfläche eingepresst und es entstehen verformte Anlenkflächen, deren Ausrichtung quer zu einer Tangente zu einem Kreis um das Verschwenkzentrum stehen. Is one of the articulation formed by one or more body edges or one or more body tips and the other articulation surface by a surface region, the body tips and body edges are press-fitted in the other articulation surface and deformed arise articulation whose position transverse to a tangent to a circle standing around the Verschwenkzentrum. Dies bewirkt eine Verzahnung zwischen Halsteil und Schaftteil, und daher eine sichere Verbindung, die auch relativ grossen Kräften auf das Kugelgelenk zwischen Grund und Halsteil widersteht. This causes a linkage between neck and shaft section, and therefore a secure connection that will withstand even relatively large forces on the ball joint between the base and neck. Der Flächenbereich kann dabei glatt oder rauh sein. The surface area can be smooth or rough. Die Möglichkeiten reichen bei glatt von unbehandelt nach spanabhebender Bearbeitung bis poliert Eine rauhe Oberfläche kann gerillt oder porös sein, sie kann geätzt, gestrahlt, gegossen oder spanabhebend bearbeitet oder sonstwie strukturierten sein. Options range in smoothly from untreated according to cutting operations to polish a rough surface can be grooved or porous, it may be irradiated, cast or machined, or otherwise patterned etched. Vorteilhaft ist dabei zu berücksichtigen, dass die beiden Anlenkflächen praktisch stufenlos gegeneinander verschwenkbar bleiben. It is advantageous to take into account that the two articulation surfaces remain virtually continuously relative to each other. Daher eignen sich rauhe Flächen eher für Linienberührung und glatte eher für Punktberührung. Therefore, rough surfaces are more suitable for line contact and smooth rather point contact.
  • In den Ausführungsbeispielen liegt der Berührungsbereich auf einer virtuellen Kugeloberfläche. In the embodiments, the contact area is located on a virtual sphere. Dies hat den Vorteil, dass die kugelgelenkartige Verschwenkbarkeit zwischen Halsteil und Schaftteil ohne zusätzliche Massnahmen gegeben ist Ist die eine Anlenkfläche, zB des Anlenkkopfes, eine Kugeloberfläche, so bildet eine mit diesem Kugeloberflächenbereich zusammenwirkende Anlenkfläche, vorteilhaft Kanten, welche quer zum stärksten der vor und nach der Verklemmung auf das Halsteil einwirkenden Drehmomente liegen. This has the advantage that the ball joint type pivoting between the neck part and shaft part without additional measures is given If the forms an articulation surface, for example of the articulation head, a spherical surface so cooperating with this ball surface area of ​​articulation, preferably edges which the front transverse to the strongest and by the jam are on the neck part torques acting. Dies verhindert die Verdrehung des Halsteils um die Halsachse, was sicherstellt, dass die gewählte Stellung zwischen Halsteil und Schaftteil beim oder nach dem Zusammenpressen dieser beiden nicht verändert wird. This prevents the rotation of the neck portion around the neck axis, which ensures that the selected position between the neck part and shaft part during or after the pressing together of these two is not changed. Es kann aber auch umgekehrt der Kugeloberflächenbereich Rillen und Kanten aufweisen. but it can also be reversed have the spherical surface area of ​​the grooves and edges. Diese stehen ebenfalls vorteilhaft quer zum stärksten auf das Halsteil wirkenden Drehmoment Zusätzlich zu den kleinflächigen Berührungsbereichen zwischen Schaftteil und Halsteil ist es auch vorteilhaft solche zwischen Halsteil und Pressteil vorzusehen. These are also advantageously transversely to the strongest acting on the neck portion of torque in addition to the small-area contact regions between the stem portion and neck portion, it is also advantageous to provide such between the neck part and press part. Es besteht deshalb mit Vorteil wenigstens eine durchgehende oder unterbrochene Linienberührung zwischen Anlenkkopf und Pressteil. Therefore, there is advantageously at least one continuous or interrupted linear contact between the articulation head and pressing member.

For fixing the articulation head 21 in the shank head 17, the screw 43 is tightened. Damit werden die beiden Kreiskanten 23,37 aufeinander zu bewegt. Thus, the two circular edges 23,37 are moved towards each other. Dabei werden die Kreiskanten 23,37 in die Kugeloberfläche des Anlenkkopfes eingepresst und verformen diesen plastisch. The circular edges are pressed into the spherical surface of the joint head 23,37 and deform it plastically. Dadurch wird eine sehr steife Verbindung zwischen dem im Knochen verankerbaren Schaftteil 13 und dem Halsteil 21 erreicht. Thereby, a very rigid connection between the anchored in the bone shaft part 13 and the neck portion 21 is achieved.

  • Im in Figur 3 dargestellten dritten Ausführungsbeispiel ist das Pressteil durch eine Überwurfmutter 53 gebildet. In the depicted in Figure 3 third embodiment, the pressing member is formed by a union nut 53rd Diese ist in ein Gewinde im Rand der Anlenkmulde 19 in die Anlenkmulde 19 einschraubbar. This can be screwed into a thread in the rim of the joint cavity 19 in the joint cavity 19th Sie kann auch analog zur Überwurfmutter in den Ausführungsbeispielen gemäss Figur 6 und 7 den Rand der Anlenkmulde 19 umfassen. It can also be analogous to the coupling nut in the embodiments according to Figures 6 and 7 include the edge of the articulation 19th Hier jedoch liegt die Überwurfmutter auch entlang praktisch eines Grosskreises am kugelförmigen Anlenkkopf 25 an und bildet so eine seitliche Führung für diesen. Here, however, the union nut is also practically along a great circle on the spherical articulation head 25 and thus forms a lateral guide for these. Diese Führung ist nicht unbedingt notwendig, da die Führung des Anlenkkopfes 25 schon durch die beiden Kreiskanten 23 und 37 erreicht ist. This guide is not absolutely necessary because the management of the joint head 25 is already reached by the two circular edges 23 and 37th Die Überwurfmutter greift analog zur Anpressplatte 31 der ersten zwei Ausführungsbeispiele mit dem Öffnungsrand 37 der Durchtrittöffnung 35 für den Halsfortsatz 27 am Anlenkkopf 25 an. The union nut engages analogous to the pressure plate 31 of the first two embodiments with the opening edge 37 of the opening 35 for the neck extension 27 on the articulation head 25th
  • Die zylindrisch abgestufte Anlenkmulde 19 weist einen ersten Radius mit dem Gewinde auf. The stepped cylindrical articulation 19 has a first radius of the thread. Ein kleinerer zweiter Radius weist beinahe den Radius des Anlenkkopfes 25 auf. A smaller second radius almost has the radius of the articulation head 25th Die Mündungskante dieses zweiten Hohlzylinders mit dem zweiten Radius bildet eine erste Kreiskante 55. Der Anlenkkopf wird beim Einpressen in diesen zweiten Hohlzylinder eingepresst, wobei sich zwischen dem Anlenkkopf 25 und der ersten Kreiskante 55 ein Klemmsitz einstellt. The opening edge of said second hollow cylinder with the second radius forms a first circular edge 55. The joint head is pressed during pressing into said second hollow cylinder being set up a clamping fit between the joint head 25 and the first circular edge 55th Eine zweite Kreiskante 23 mit kleinerem Radius als die erste und eine Körperspitze 57 auf der Achse 33 der Zylinderbohrung am Grund der Anlenkmulde 19 liegen annähernd auf einer Kugeloberfläche mit demselben Radius, wie die Kugel des Anlenkkopfs 25. Beim Einpressen des Anlenkkopfes 25 in die Anlenkmulde 19 kerben diese sich in die Oberfläche des Anlenkkopfes ein. A second circular edge 23 with a smaller radius than the first and a body tip 57 on the axis 33 of the cylinder bore at the base of the articulation 19 are located approximately on a spherical surface having the same radius as the ball of the Anlenkkopfs 25.

Die Trennung von Halsteil 21 und Exzenterring 59 ist deshalb notwendig, weil der Exzenterring 59 nicht durch die Durchtrittöffnung 37 hindurch passt. The separation of the neck portion 21 and eccentric ring 59 is necessary because of the eccentric ring 59 does not fit through the passage opening 37 therethrough. Wenn der Halsfortsatz 27 in den Anlenkkopf 25 einsetzbar ist, kann der Exzenterring 59 auch einstückig mit dem Halsfortsatz 27 hergestellt sein. When the collar extension can be inserted into the joint head 25 27, the eccentric 59 may be also produced in one piece with the neck extension 27th
  • Da die Erfindung unabhängig von der Form des Schaftteils oder Schaftteils 13 ist, ist in den Figuren 4 bis 9 lediglich der Schaftkopf 17 mit Halsteil 21 und Pressteil, zT mit. Since the invention is independent of the shape of the shaft part or the shaft part 13, only the shaft head 17 with neck portion 21 and pressing part, partly with in Figures 4 through. 9 zT ohne Exzenter und Kopfkalotte 29 dargestellt. and partly without the eccentric ball head 29 shown.
  • Figur 4 zeigt ein viertes Ausführungsbeispiel mit einer Anlenkmulde 19 im Schaftkopf 17 mit etwa halbkugeliger Anlenkfläche 67, einer Überwurfmutter 53 mit konkaver, etwa halbkugeliger Anlenkfläche 69 und einem Halsteil 21 mit zylindrischem Anlenkkopf 25. Der zylindrische Anlenkkopf 25 weist zwei Kreiskanten 71,73 auf, von denen eine mit der Anlenkfläche 67 der Anlenkmulde 19 und die andere mit der Anlenkfläche 69 der Überwurfmutter 53 zusammenwirkt. Figure 4 shows a fourth embodiment with an articulation 19 in the shaft head 17 with approximately semi-spherical articulation surface 67, a cap nut 53 with a concave, approximately semi-spherical articulation surface 69 and a neck portion 21 with a cylindrical articulation 25. The cylindrical articulation head 25 has two circular edges 71,73 on, of which cooperates with one of the articulation surface 67 of the articulation 19 and the others with the articulation surface 69 of the cap nut 53rd Die Kreiskanten 71,73 liegen auf einer virtuellen Kugeloberfläche mit etwa dem gleichen Radius wie die Kugeloberflächen 67,69 von Anlenkmulde 19 und Überwurfschraube 53. Zur Justierung des Kugelradius der virtuellen Kugeloberfläche genügt es, die Länge des Anlenkkopfes 25 zu verändern. The circular edges 71,73 lie on a virtual spherical surface having about the same radius as the spherical surfaces 67,69 of articulation 19 and cap screw 53. In order to adjust the sphere radius of the virtual sphere surface, it suffices to change the length of the articulation head 25th Der Radius der virtuellen Kugel ist vorteilhaft etwas grösser als der Radius der Hohlkugeloberflächen der beiden Anlenkflächen 67,69. The radius of the virtual sphere is advantageously somewhat greater than the radius of the hollow spherical surfaces of the two articulation surfaces 67,69. Eine genügende Genauigkeit der Übereinstimmung der beiden Kugelradien ist einfach zu erreichen, da die Anlenkflächen 67,69 bzw. die Kreiskanten 71,73 plastisch verformbar sind. A sufficient accuracy of the match of the two spherical radii is easy to achieve, since the articulation surfaces 67,69 or the circular edges 71,73 are plastically deformable.
  • In Figur 5 ist ein fünftes Ausführungsbeispiel dargestellt. In Figure 5, a fifth embodiment is illustrated. Bei diesem ist die Anpressplatte 31 keine Überwurfmutter mit einem Gewinde, sondern hält mit einem Klemmsitz im Schaftkopf 17. Sie weist eine hohlkugelige Anlenkfläche 69 auf, welche mit einer unterbrochen Kreiskante 73 an einem teilweise zylindrischen Anlenkkopf 25 zusammenwirkt. In this, the pressure plate 31 is not a union nut with a thread, but keeps a clamping fit in the shaft head 17. It comprises a hollow spherical articulation surface 69 which cooperates with an interrupted circular edge 73 to a partially cylindrical articulation 25th Die Kreiskante 73 ist durch Einschnitte in den Anlenkkopf 25 zu einer Reihe von Körperspitzen 47 aufgelöst, deren Spitzen 49 sich beim Festschlagen der Anlenkscheibe 31 in den Schaftkopf 17 in die Anlenkfläche 69 eingraben. The circular edge 73 is dissolved by cuts in the articulation 25 to a series of body tips 47 whose tips 49 dig in hard hitting the Anlenkscheibe 31 in the shaft head 17 in the articulation 69th Die Anlenkmulde 19 weist zwei Kreiskanten 23, 23' auf, welche mit einer Kugeloberfläche 75 am Anlenkkopf 25 zusammenwirken. The articulation 19 comprises two circular edges 23, 23 ', which cooperate with a spherical surface 75 at the articulation 25th Auch in diesem Ausführungsbeispiel ist die Übereinstimmung der Radien der Kugeloberfläche 75und der Kreiskante 73 am Anlenkkopf 25, mit den Radien von Virtueller Kugeloberfläche, auf der die Kreiskanten 23,23' liegen und der Anlenkfläche 69 an der Anpressscheibe 31 relativ leicht zu erreichen, da die gewünschte Verformung der Berührungsbereiche grössere Toleranzen zulässt, als es eine Verpressung zweier kongruenter Anlenkflächen kann, Die Verklemmung zwischen Schaftteil 13 und Anpressscheibe 31 kann direkt über einen Konus erreicht werden. Also in this embodiment, the coincidence of the radii of the spherical surface 75 and the circular edge 73 on the articulation head 25, with the radii of virtual spherical surface, on which the circular edges 23,23 are 'and relatively easy to achieve the articulation surface 69 of the pressure disc 31, because the desired deformation of the contact regions of larger tolerances allow, as it can be a compression of two congruent articulation surfaces, the clamping between the shaft part 13 and pressing disk 31 may be accessed directly by a cone. Besser wird jedoch die Verklemmung der Anpressscheibe 31 wie dargestellt über eine Keilklemmung mit einem zB C-förmig die Anpressscheibe umgreifenden Keil 76 erreicht Better, however, the jamming of the compression plate 31 is shown as a wedge clamping eg with a C-shaped reach the pressure disc engages around the wedge 76
  • Das in Figur 6 dargestellte sechste Ausführungsbeispiel weist einen kegelförmigen Grund 77 der Anlenkmulde 19 und einen kugelförmigen Anlenkkopf 25 des Halsteils 21 auf. The illustrated in Figure 6, the sixth embodiment has a conical base 77 of the articulation 19 and a spherical articulation head 25 of the neck portion 21st Die Mantelfläche des Grundes 77 weist Einschnitte 79 in Richtung der Mantellinien durch die Kegelspitze auf. The lateral surface of the substrate 77 has incisions 79 in the direction of the generating lines on by the conical tip. Dadurch ergeben sich zwischen den Einschnitten 79 Kanten 81 quer zu einer Rotationsrichtung um die Achse 33. Die Anpressscheibe 31 ist mit einer Überwurfmutter 53 am Schaftkopf 17 befestigt. This results in the notches 79 between edges 81 transversely to a direction of rotation about the axis 33. The pressure disc 31 is fastened with a cap nut 53 on the shaft head 17th Das Halsteil 21 ist einstückig mit einem Exzenter 83 ausgerüstet. The neck portion 21 is integrally equipped with an eccentric 83rd Die Anpressscheibe 31 ist C-förmig. The pressure disc 31 is C-shaped. Die C-Öffnung weist eine Weite auf, welche es erlaubt, die einen Halsbereich 85 zwischen Anlenkkopf 25 und Exzenter 83 des Halsteils 21 durch diese C-Öffnung hindurch in die Durchtrittöffnung 37 der Anpressscheibe 31 einzuführen. The C-opening has a width which allows the introduction of a neck region 85 between the articulation head 25 and eccentric 83 of the neck portion 21 by these C-opening into the passage opening 37 of the pressure disc 31st Die Überwurfmutter 53 ist entweder auch C-förmig oder weist einer Öffnungsweite auf, die es erlaubt, die Überwurfmutter 53 über den Exzenter 83 hinab oder über den Anlenkkopf 25 hinauf auf das Halsteil 21 zu schieben. The cap nut 53 is either also C-shaped or has an opening width, which makes it possible to slide the cap nut 53 via the eccentric 83 or down through the articulation head 25 up to the neck portion 21st Im letzteren Fall muss zuerst die Überwurfmutter über den Anlenkkopf 25 geschoben und danach die Anpressscheibe 31 zwischen Anlenkkopf 25 und Überwurfmutter 53 eingeschoben werden. In the latter case, first the nut must pushed over the articulation head 25 and thereafter, the compression plate 31 are inserted between the articulation head 25 and nut 53rd Die Anlenkscheibe 31 ist in diesem Beispiel gegenüber der Überwurfmutter 53 verdrehbar. The Anlenkscheibe 31 is rotated in this example opposite the nut 53rd Dies hat den Vorteil, dass beim Anziehen der Überwurfmutter 53 kaum ein Drehmoment auf das Halsteil 21 übertragen wird. This has almost no torque is transmitted to the neck part 21 when tightening the nut 53 the advantage. Die Öffnungskante 37 wird beim Anziehen der Überwurfmutter 53 gegenüber dem Anlenkkopf 25 nicht verdreht, sondern lediglich gegen diesen gepresst. The opening edge 37 is not twisted when tightening the cap nut 53 with respect to the articulation head 25, but simply pressed against the latter. In nicht festgezogenem Zustand kann das Halsteil 21 um die Halsachse 33 verdreht werden. In non-tightened state, the neck portion can be rotated around the neck axis 33 21st Dadurch kann der Exzenter 83 in die gewünschte Lage gebracht werden. Thus, the eccentric can be brought into the desired position 83rd
  • Figur 7 zeigt anhand eines siebentes Ausführungsbeispiels eine sehr einfache Variante der Anpressplatte und eine weitere Möglichkeit der Kombination von zylindrischen und Kugelförmigen Körpern und Öffnungen zur Erreichung einer bereits mehrfach ausgeführten kugelgelenluartigen Verbindung zwischen Anlenkmulde und Anlenkkopf bzw. zwischen Schaftkopf 17 und Halsteil 21. In diesem Beispiel weist die Anlenkmulde einen halbkugelförmigen Grund 67 auf, der mit einer Kreiskante 23 eines zylindrischen Anlenkkopfes 25 zusammenwirkt, zur Anpressscheibe 31 hin ist der Anlenkkopf jedoch kugelig geformt, so dass die kreisrunde Öffnungskante 37 der Anpressscheibe 31 am Anlenkkopf in jeder Schwenkstellung desselben gleichermassen anliegt. Figure 7 shows by way of a seventh embodiment of a very simple variant of the pressure plate and a further possibility of the combination of cylindrical and spherical bodies and openings to achieve an already repeatedly executed kugelgelenluartigen connection between the articulation and the articulation head or between stem head 17 and neck portion 21. In this example , the articulation a hemispherical base 67, which cooperates with a circular edge 23 of a cylindrical articulation head 25, the pressure disc 31 toward however, the joint head is spherical shaped so that the circular opening edge 37 of the pressure disc 31 of the same in any pivoting position of the articulation head are equally applied. Die Anlenkscheibe 31 ist mit zwei Schrauben 43 an den Schaftkopf 17 anschraubbar. The Anlenkscheibe 31 is screwed with two screws 43 to the shaft head 17th
  • Figur 8 illustriert noch, dass die Erfindung auch ohne Anpressscheibe 31 auskommt Das Halsteil 21 ist in diesem achten Ausführungsbeispiel zylindrisch ausgebildet und weist dank einer Abstufung das Anlenkkopfes 25 zwei Kreiskanten 23,23' auf einer virtuellen Kugeloberfläche auf. Figure 8 illustrates yet that the invention makes do without the pressure disc 31. The neck portion 21 is cylindrical in this eighth embodiment, and has, thanks to a gradation, the joint head 25 has two circular edges 23,23 'on a virtual spherical surface. Diese Kreiskanten 23,23' arbeiten zusammen mit der Hohlkugeloberfläche der Anlenkmulde 19. Das Halsteil 21 ist nun hohl ausgebildet und eine Schraube 87 sitzt derart in dieser Höhlung 89, dass Ihr Gewindeabschnitt durch eine stirnseitige Öffnung im Halsteil austritt und im Grund der Anlenkmulde einschraubbar ist Am kegelstumpfförmigen Schraubenkopf ist eine Kreiskante 91 ausgebildet, die mit einer Hohlkugeloberfläche am Grund der Höhlung 89 zusammenwirkt Das Halsteil 21 ist einstückig mit dem Exzenter 83 ausgebildet. These circular edges 23,23 'cooperate with the hollow spherical surface of the articulation 19. The neck portion 21 is now made hollow and a screw 87 is seated in such a manner in this cavity 89 that your threaded portion exits through a front opening in the neck portion and screwed in the base of the articulation is at the frusto-conical screw head, a circular edge 91 is formed which cooperates with a hollow spherical surface on the base of the cavity 89, the neck portion 21 is integrally formed with the eccentric 83rd In festgezogenem Zustand der Schraube 87 sind die Kanten 91, 23, 23' in die Kugeloberflächen eingepresst und verhindern dadurch zuverlässig eine Verschwenkung des Halsteils 21 gegenüber dem Schaftkopf 17. Dann fallen die Kugelmittelpunkte der verschiedenen Kugeloberflächen vorteilhaft praktisch zusammen. In tightened condition of the screw 87, the edges 91, 23, 23 'are pressed into the spherical surfaces and thereby prevent reliably a pivoting of the neck portion 21 relative to the shank head 17, then drop the ball center points of the various spherical surfaces advantageously virtually together. Kleinere Abweichungen von einer exakten Übereinstimmung der Kugelmittelpunkte werden jedoch durch die Verformungen kompensiert. Minor deviations from an exact match of the ball centers are offset by the deformations.
  • Die Ausführungsbeispiele sind ferner dahingehend abwandelbar, dass die Anlenkmulde im Halsteil und der Anlenkkopf im Schaftkopf ausgebildet ist. The exemplary embodiments are further be modified to the effect that the joint cavity in the neck portion and the joint head is formed in the shank head. Der Halsfortsatz muss mit dem Anlenkkopf nicht einstückig ausgebildet sein, sondern kann als ein im Anlenkkopf festmachbarer Stiel vorgesehen sein. The neck extension need not be formed integrally with the joint head, but can be used as a festmachbarer in the articulation handle can be provided. Die Ausbildung des Pressteils ist weitgehend unabhängig von der Ausbildung der Anlenkflächen zwischen Anlenkmulde und Anlenkkopf, so dass die unterschiedlichsten Kombinationen unter den dargestellten und erwähnten Ausführungsvariationen möglich sind. The formation of the pressed part is largely independent of the formation of the articulation between articulation chamber and the articulation head, so that a wide variety of combinations among the shown and mentioned embodiment, variations are possible.
  • Weiter ist zu erwähnen, dass zB der Anlenkkopf 25 kein Vollkörper sein muss. It should also be noted that as the joint head 25 must be no solid body. Er kann beispielsweise wie in Figur 9 bis 11 dargestellt, aus Einzelteilen zusammengesetzt sein. It can, for example, as shown in Figure 9 to 11, be composed of individual parts. Figur 9 und 10 zeigen die Ansichten von zwei zusammensteckbaren plattenförmigen Teilen 93 und 95. Zusammengesetzt ergeben die Teile 93,95 ein Halsteil 21, das anstelle des Halsteils 21 in Figur 2 eingesetzt werden kann. Figure 9 and 10 show the views of two-together plate-shaped parts 93 and 95. Composite give the parts 93,95 a neck portion 21 which can be used in place of the neck part 21 in FIG. 2 Die Teile 93,95 sind einfach in der Herstellung. The parts 93,95 are easy to produce. Sie können zB mit Laser aus einer Platte geschnitten oder auch gegossen werden. They may be cut or laser of a plate and poured. Die Randfläche 97 muss nicht eine Kugeloberfläche sein. The edge surface 97 need not be a spherical surface. Durch die Einpressung in die Anlenkmulde werden die Kanten 99 derart verformt, dass sowohl eine grossflächige Auflage als auch eine sehr gute Verzahnung zwischen Schaftkopf 17 und Halsteil 21 erreicht ist Der Teil 93 in Figur 9 ist mit dem Schlitz 101 über den Schlitz 103 am Teil 95 in Figur 10 hinweg auf dieses Teil 95 aufschiebbar, so dass alle Kanten 99 auf einer gemeinsamen Kugeloberfläche liegen. By press-fitting in the joint cavity edges 99 are deformed in such a manner is that both a large-area support as well as a very good interlock between stem head 17 and neck portion 21 reaches the portion 93 in Figure 9 is provided with the slot 101 through the slit 103 at the portion 95 so that all the edges 99 are in Figure 10 away pushed onto this part 95, on a common spherical surface. Im Halsfortsatz 27 ist in beiden Teilen 93,95 eine Nut ausgebildet, in welche eine Schraube 105 einschraubbar ist. In the neck extension 27 in two parts 93,95 a groove is formed, into which a screw 105 is screwed.
  • Der Halsfortsatz 27 aus beiden Teilen 93,93 bildet ein Kreuz mit einer zentralen, quadratischen Ausnehmung. The neck extension 27 from both parts 93,93 forms a cross with a central, square recess. Auf dieses Kreuz ist nun der Exzenterring 59 aufsetzbar. On this cross the eccentric ring 59 is now placed. Dank der Kreuzform des Halsfortsatzes 27 und einer entsprechenden Ausnehmung im Exzenterring ist eine Verdrehung des Exzenterringes 59 gegenüber dem Halsteil 21 verunmöglicht. Thanks to the cross shape of the neck extension 27 and a corresponding recess in the eccentric rotation of the eccentric ring 59 with respect to the neck portion 21 is impossible. Zur Fixation des Exzenterringes 59 auf dem Halsfortsatz 27 und der beiden Teile 93,95 aneinander kann nun die Schraube 105 eingeschraubt werden, was eine Verklemmung zwischen den Teilen 93,95 einerseits und dem Exzenterring 59 andererseits bewirkt. For fixation of the eccentric ring 59 on the neck extension 27 and the two parts 93,95 together, the screw can be screwed now 105, which causes jamming between the parts 93,95 on the one hand and the eccentric ring 59 on the other. In Figur 11 ist das zusammengesetzte Halsteil 21 mit Exzenterring 59 in einer Aufsicht dargestellt. In Figure 11, the composite neck portion 21 is shown with the eccentric ring 59 in a plan view. In dieser Ansicht ist erkennbar, wie die Randflächen 97 der beiden Teile orthogonal zur Plattenebene ausgebildet sind. In this view it can be seen how the edge surfaces 97 of the two parts are formed orthogonal to the plate plane.
  • In Figur 12 ist ein zehntes Ausführungsbeispiel dargestellt, in welchem das Halsteil 21 aus zwei Teilen 93,95 zusammengesetzt ist Das Halsteil 21 entspricht bis auf die Form des Anlenkkopfes 25 exakt dem in Figuren 9 bis 11 dargestellten Halsteil 21. Der Schaftkopf 17 ist mit einer zylindrischen Anlenkmulde 19 ausgestattet, in welcher eine Körperkante 23 ausgebildet ist, an der die Kanten 99 des Halsteils 21 anliegen. In Figure 12, a tenth embodiment is shown, composed in which the neck portion 21 into two parts 93,95, the neck part 21 corresponds to the shape of the joint head 25 exactly 21 the neck portion shown in Figures 9 to 11 The shaft head 17 is provided with a equipped cylindrical articulation 19, in which a body edge 23 is formed where the edges 99 abut the neck portion 21st Das Halsteil 21 ist mit einer Anpressscheibe 31 gegen den Grund der Anlenkmulde 19 gepresst. The neck portion 21 is pressed with a pressure disc 31 against the base of the articulation 19th Die Kraft, mit der die Anpressscheibe 31 gegen den Schaft 13 gepresst wird, ist durch einen Spannbügel 107 auf diese übertragen. The force with which the compression plate 31 is pressed against the shaft 13, is transmitted through a clamping bracket 107 thereto. Der Spannbügel 107 liegt auf der Aussenseite der Anpressscheibe 31 an und hintergreift einen Hinterschnitt 109 im Schaftkopf 17. Er ist aus einem federnden Material gefertigt, so dass eine relativ grosse Kraft auf die Anpressplatte ausgeübt wird. The clamping bracket 107 is located on on the outer side of the pressure disc 31 and engages behind an undercut 109 in the shank head 17. It is made of a resilient material, so that a relatively large force is exerted on the pressure plate. Der Spannbügel 107 kann auch unmittelbar die Anpressscheibe 31 bilden. The clamping bracket 107 can also form the pressure disc 31 directly.
